Judge Judy

In anticipation of her Jan. 12 debut on E!'s Fashion Police, the 54-year-old comedienne talked to PEOPLE about how she'll fill the very large shoes of the late Joan Rivers – and how she's going to look while doing it.

Modern technology can be tough for any 71-year-old to pick up, but television's Judge Judy was a quick learner when she was introduced to Grindr in an episode that aired Monday.

While hearing a case involving defendant Aaron Murphy and the much-older plaintiff Christopher Starnes, Judge Judy posed an obvious question: Where had the two men met?

Murphy attempted to explain the hookup app with a polite euphemism: They'd met, he said, on "a social web site." Upon further examination, the defendant admitted Grindr was "a social app that tells you where homosexual males are." But, he assured the judge, he was only on it trying to "make friends."

"I'm really fine," she tells the Web site. "I wanted to go back to work this afternoon. I'm exhausted. I'm tired. A lot of things just zoned together, including the bad news of the world. At my age, I know my body. My body is fine." – Dahvi Shira
